The Printrbot PLA filament is a 1 kg spool of metallic charcoal gray color PLA (polylactic acid) plastic formed as a continuous, 1.75 mm diameter filament. The filament is used to fill the material reservoir of a 3D printer (sold separately) and has a print temperature range from 180 to 220 degrees C. It is rolled on a spool for mounting onto a 3D printer's spool holder (sold separately). The filament is mixed with reflective fibers to appear shiny. PLA plastic is chemically inert, has high strength, and is less prone to warping during printing than ABS (acrylonitrile butadiene styrene) plastic when used in printers without a heated bed.

Printrbot manufactures desktop 3D printers and accessories. The company is headquartered in Lincoln, CA.
